To (til whom it may concern:

Be it known that I, AUeUsT BLELE, a citizen of the United States, residing at New Haven, in the county of Franklin and State of Missouri, have invented new and useful Improvements in Insulators, of which the following is a specification.

My invention has relation to that class of insulators that are connected with the crossarms of telegraph-poles to support the linewires of the telegraph; and it has for its object the provision of improvements whereby with for supportin the glass knobs usually employed; the insu ator is less liable .to be broken or shot to pieces by mischievous boys with .toy guns and slings; it is inclosed in the arm, so as to be protected; the Wire is not liable tofall to.the ground if the insulator should be broken; it can of anyreadily be made to suit an arm or wire size; it is more economical than the threaded pin and knob; tied in quick time than by can be employed at either the top or bottom of the cross-arm; can be easily and quickly replaced in case of necessity.

screwit is more safely the knob and tie;

The drawings are an essential part of'this' specification and are to such, and represent, in-

Figure 1, aperspective view of a pole and cross-arm equipped with my improved insulators. Fig. 2 is a perspective view of one of my improved insulators detached. Fig. 3 is a longitudinal sectional view of the crossarm with the insulator secured therein. Fig. 4 is an end view.

My impro ved insulator is preferably employed near the edge of the cross-farm and when so used may be introduced near the lower or upper edge, as mayseem best. It is constructed of glass and may be made round or cylindrical in form, with one or more holes a made longitudinally through it for a line-wire or line-wires and another hole I; for the tie-wire. more cylindrical grooves 0 may be formed in the outside for the tie-Wires. formed longitudinally in the the outside to the hole a, so

wire may be simply laid therein through a slit e, made in the cross-arm from the outside to the hole f, which may be bored throu h the arm as near theedge as may be Wante After the line-Wire is put in place in the insulator the latter may be turned slig keep the line-wire from accidentally dropto maintain it from turning or from otherwise becoming displaced a longshanked nail 9 may be driven into the crossarm and the transverse groove in the side of the insulator, and so key the latter in position. Any other suitable means may be employed for this purpose.- After all of the parts are in place, as stated, the tiewire h, passing through the hole I) or laid in the groove 0, may betwisted around the linewire or its supports in any suitable and convenient Way to hold it in lace and not disturb its insulation. -'l-h"e ole e for the insulator may be bored through the cross-arm at or near its center; but in that case the slit f would have to cut through a good deal of .the substance formin the cross-arm. But

little time is require to slip the line-wire I through the slit in the cross-arm and sides of the insulator, and when the insulator is keyed and the line-wire tied, which can be done in an inconsiderable amount of time, all things are as securely in place as need be. The line-wire may be taken out without cutting the line-wire, and repairs or changes can be made in an entirely practical Way and most, expeditiously. As before stated, the line-wire is not likely get outof the way, so as to cause accidents.

Changes may be made in the form and arrangement of parts within the limits of mechanical skill without departing from the nature or spirit of the invention.
